Table 5. AUXR1: Auxiliary Register 1
Reset Value = XXXX 00X0
Not bit addressable
User software should not write 1s to reserved bits. These bits may be used in future 8051 family products to invoke new feature. In that case, the reset
value of the new bit will be 0, and its active value will be 1. The value read from a reserved bit is indeterminate.
Application
Software can take advantage of the additional data pointers to both increase speed and reduce code size, for
example, block operations (copy, compare, search ...) are well served by using one data pointer as a ’source’
pointer and the other one as a "destination" pointer.
